Shopping bags have become the main source of "white pollution", and in the future, people's governments at all levels, ministries and commissions should prohibit the production, sale and use of ultra-thin plastic shopping bags, and implement a paid-use system for plastic shopping bags. Starting from June 1, 2008, a paid-use system for plastic shopping bags will be implemented in all supermarkets, malls, farmers' markets and other commodity retail outlets, and plastic shopping bags shall not be provided for free.
